Kenworth 850 Off Highway

[RCP57]

Thanks very much to all of you. I actually enjoyed watching the video myself because it made me stop and think about the process of making certain parts.

Thanks again to those that helped keep me motivated though out the build!

Mario, you are probably right. It may just be a while.

Wow, this is cool! That's a beast of a setup! Really puts things in perspective with both of those dumps sitting on the deck!!!

Keep up the good work Reg!,

Thanks Alex! My wife and I spent some time over the weekend camping in an area where some real off-highway trucks still operate hauling logs. We passed a loaded Hayes HDX yesterday on our way home. I must say that you feel pretty small in a full size pickup with a camper when one drives by on a two lane road! With 15' bunks they own the majority of the road and you get what's left! I pulled over as far as I could and we waited for the truck to pass! There aren't many of these trucks in use anymore so the remaining drivers are the best of the best. No worries about them not knowing if they can pass or not!

Reg,

Thanks for posting your build video. I can't say it enough, you skills are just amazing! I actually watched it twice and paused several times just to take in the detail and complexity of this project. You are the master of metal for sure.

[Supermario]

Don't sell yourself short Reg. You may not think it'll happen but.....something tells me there will be another epic build coming from the RCP camp in the future.
It's in your nature! You have to!

[modelman]

That would be very scary coming down the road at you!!

[JohnStilwell]

Wow, I mean... have the road dude, it's all yours!! What's he grossing, 160 Tons or more? Cool vid Reg.

Haha, One of our friends is a driver. He has a bumper sticker on the rad guard that says "As a matter of fact I do own the road". Very fitting I think. I believe the trucks were designed to carry 100+ tons of logs but of course when conditions are good and the roads aren't too steep they load on a lot more. Most of the places they are logging now have some nasty grades with a lot of switchbacks so the loads are more moderate like in the video. Even with a smaller load there is close to 3 highway truck loads on there! Very cool trucks in person.

I like this video on YouTube....http://youtu.be/7UHChCRe6hI?list=FLr...tJ-DusnO8Onw7A These trucks are the real deal!

[TRUCKMAKER]

Thats insane, you definitely need your sea legs for that ride the way it sways back and forth.

[JohnStilwell]

LOL, love it, yes, TOTALLY fitting Reg.
Agreed, INSANE. Imaging the feel of that 100+ ton 'push' going down hill, dang what a rush.
Sea legs and balls of titanium!!! like basketball size!

On the other side of the world, Canada and New Zealand are similar in so many ways, climate etc, but it is the Logging Industry that is the closest, Canada and NZ are the only two in the world that Log big tree's, mostly because the trees come from Canada, Pinus Radiata (Pine) is the most common but there is also Redwood and Kauri Logging which is unique and demands very big gear, check the video link below to see some current Pine operations in NZ

Interesting video Paul. You are correct that we have a very similar forest industry. A lot of good old BC equipment has found a new home in NZ. Even some of the manufacturers have set up shop there build yarders and log loaders. There was a big auction here on the island back in 2008 and a lot of the equipment was sold into New Zealand. At least that stuff was spared the fate of the scrap yard and has been put to good use.

[PaulNZ]

Yes, I spent many years working for Hitachi Machinery as a Diesel Mechanic, a lot of the crews had Hitachi and John Deere machines and I spent many days and nights working on their Madill swing yarders among others.

[Supermario]

in the past we have sold used 535 CAT skidders to Australia. We had to strip it right down to pieces and clean it and reassemble. If they found more than two hands of dirt at shipping, it was a major fine on us. Makes sense though, prevent introducing insects etc to a foreign continent .

Reg,

I just stumbled onto the slide show video, wow!

I am trying to get started on the truck chassis under my NyLint dragline. I know with all your skill and experience this will be hard to answer but what did you use for plans or design ideas as you built the logging truck?

Could you say something about the drive train? I saw one picture that looked like an off the shelf gear going into the diff but is it a solid axel or a live diff?

What sort of mill are you using for this sort of stuff? I purchased a 10" lathe a few weeks back and of course now I realize I ALSO need a mill!

Thanks for the inspiration, now if I can keep away that overwhelming feeling I get when I think about working on my stuff.

Thanks Jim. I actually get some enjoyment out of watching that video myself. It reminds me of how much work it really was but also the processes involved to make each part. I didn't go by any plans to build it. I took a ton of pictures of the real trucks along with some measurements of critical parts. From there I just tried my best to make the model look like the real thing where I could. The rear ends were built using HPI Savage diff gears. I used the older style that don't have the drive cup attached and then made my own axle shafts to fit the side gears. Both diffs are open. The drive motor is from an 18v drill. I have a BF30 mill with a SINO DRO. Having a DRO is awesome for someone like me that doesn't know anything about machining. It's kinda like having the answers for a test you haven't studied for! Don't let yourself get overwhelmed! You will do fine, all you need is confidence because you already have talent! I am just about to start scratch building a pair of Rockwell 4640 diffs for a Hayes truck. I may need to read my own words of encouragement there to keep from giving up on them!lol The biggest problem for me will be trying to make 2 that are the same....

Reg,

Not only do you have some exceptional talent you sir are also a diplomat! Thanks for the very encouraging reply! I'm heading out the the shop to see if I can put some of your encouragement to good use!

Reg, I enjoy watching all those videos. I even crack a smile on all the "N" scale commentary. That is still my favorite truck.

[Lil Giants]

Some great shots with the scenery Reg, the KW is your best ever masterpiece that I don't think you'll ever top.

But imagine if it had a gravel dump behind it, how much more use you'd get out of it instead of being just a pretty trk driving around?

Thanks very much. I try to keep the commentary clean but every now and then some bad words leak out.lol

Thanks Joe. The KW is definitely my defining piece and I think you are right, I will never top it. The main reason I think that way is to be honest I doubt I could ever devote that much time to another build. It really was my full time job for several months and I became very emotionally invested in the story behind the real truck.

I know what you are saying about the dump option. As cool as it is to have an RC logging truck like no other it is not very practical. If however, I were to build a log loader that may change....
